94 Ignition Control Module Problem

I have a 94 F150 Super Cab 5.0.
It would not start so I had I shop look at it and they diagnosed on the test equipment that the ignition control module was not working and they replaced it.
A few days later it died again and they replaced it.
It lasted two weeks and it too failed yesterday.
They replaced it with motorcraft too.
What could be causing this part to blow, there must be something before/after that part that is causing it to blow out.

Any suggestions on what that might be?

Thanks for your help,
Jeff

I would doubt that there was anything wrong with any of the Modules.
My guess would be you have a bad "PIP" sensor inside the distributor.

By the way make sure they are replacing the ICM with a BLACK one and NOT a GRAY ICM.

By the way if the ICM had a date code of 4L18B it is on recall and Ford should replace it for free.

The above was for the remote mounted ICM.

Yes they had some bad ICM mounted on the distributor and they replaced them with some better updated ones.
But I would have thought yours would have been changed out years ago with the better ones.
Your problem sounds more like a PIP sensor then the ICM but it could be either.
